"There's no reason to actually try to physically attack someone, especially a politician."
There are PLENTY of reasons to attack people, and more so in the case of many politicians. Consider how much better off the world would have been without Hitler taking control, or Stalin. Consider how much better off tens of thousands American Japanese, Italian and German would have been without FDR. How about never having the "Trail of Tears"?
Throwing a shoe at Hillary was a waste of time. Politicians are the biggest threat to our freedom and our Constitution. There may come a time when violence is needed to restore what is being taken from us. We are not there yet, but are heading in that direction.
